Objectives: The aim of this study was to examine changes in the bones of adolescents with type-1 diabetes mellitus (T1DM) using fractal dimension (FD) analysis method and panoramic radiomorphometric indices. Methods: Fractal dimension values and radiomorphometric measurements of 36 children with T1DM and 36 healthy individuals were compared using panoramic radiographs. The panoramic mandibular index (PMI), mental index (MI), mandibular cortical width (MCW), amount of alveolar bone resorption (AABR), antegonial index (AI), and gonial index (GI) were measured. Mandibular cortical index (MCI) was recorded as C1, C2, and C3 classes. Results: For the angulus and corpus regions, the T1DM patient group had lower FD values, and there was a statistically significant difference between the T1DM patient group and the control group (P = 0.003, P = 0.029). Mental index, MCW, and AI values were higher in the control group than in the T1DM patient group and were statistically significant (P = 0.014, P = 0.001, P < 0.001, respectively).

Ultrasound (US) often serves as the initial imaging modality for evaluating these lesions, assisting in diagnosis, and guiding clinical decisions. Objectives: This study aimed to delineate the characteristic US features of intra-abdominal cystic lesions not arising from the liver, spleen, or kidney in children and to assess their diagnostic value for providing definitive diagnoses. Methods: Conducted in the radiology department of pediatric hospitals affiliated with Mashhad University of Medical Sciences from 2019 to 2022, this cross-sectional study examined 104 children with cystic abdominal lesions. Patient demographic data and US characteristics were documented. Definitive diagnoses were established through histopathological reports, surgical outcomes, or clinical follow-up. The accuracy of US findings was evaluated against these definitive diagnoses, with the sensitivity and specificity of US features for various intra-abdominal cystic lesions being calculated. Results: The most frequent cystic lesions identified were perinatal ovarian torsion (22.1%) and duplication cysts (18.2%). Ultrasound achieved a sensitivity and specificity of 82.61% (95% CI = 0.6 - 0.94) and 100% (95% CI = 0.94 - 1), respectively, in diagnosing perinatal ovarian torsion and 89.47% (95% CI = 0.65 - 0.98) and 94.11% (95% CI = 0.86 - 0.97) in diagnosing duplication cysts.

Despite advancements, there are still gaps in our understanding. Objectives: This study aimed to explore factors influencing wound healing in children with second-degree burns to guide clinical treatment and nursing practices. Methods: We conducted a retrospective analysis of children with second-degree burns treated in our burn surgery department from January 2020 to December 2022. Based on the events per variable (EPV) rule, 220 children were included. They were categorized based on the quality of wound healing 14 days post-admission (good or poor), evaluated by the healing rate and scar formation. Children's clinical data were extracted from medical records for analysis. Binary logistic regression identified factors associated with poor healing outcomes in second-degree burns. Results: Among 220 patients with secondary burns, 166 (75.46%) experienced good wound healing, while 54 (24.54%) had poor outcomes. The Hosmer-Lemeshow test indicated a good model fit (χ2 = 9.739, P = 0.28). Significant variables included burn area (odds ratio [OR] = 1.217, 95% confidence interval [CI] = 1.109 - 1.335, P < 0.05), number of drug changes (OR = 1.902, 95%CI = 1.392 - 2.599, P < 0.05), white blood cell count (OR = 1.076, 95%CI = 1.008 - 1.150, P < 0.05), neutrophil count (OR = 1.080, 95%CI = 1.018 - 1.146, P < 0.05), and neutrophil ratio (OR = 1.040, 95%CI = 1.002 - 1.081, P < 0.05).

Results: Out of 156 orogastric tubes, 85.3% were accurately placed in the stomach according to radiological assessment, with ultrasonography confirming 88.5% of stomach placements. Accuracy rates were 67.3% for radiological evaluation and 60.3% for ultrasonography in determining the accurate position. The agreement assessment demonstrated a sensitivity of 68.6% and a specificity of 46.3%.

Objectives: The aim of this study was to conduct a cost-effectiveness analysis of this program integrated into Iran's health system. Methods: We examined the cost-effectiveness of AABR and OAE screening procedures in infants less than 1 month old. TreeAge 2022 software was used for cost-effective modeling. In this study, QoL and QALY were considered as the outcome measures. To evaluate the robustness of the modeling results, we used one-way sensitivity analysis. A ± 20% variation was utilized to determine target variables and estimate the costs per identification. Results: In 2022, a total of 1,106,072 babies were born in Iran, of whom 1,006,293 underwent hearing impairment screening (coverage rate: 90.97%). Overall, 3,359 of the newborns screened were diagnosed with hearing problems, indicating a mean prevalence of 3.3 per 1000 births. The ICER was equal to 3297.2 US PPP (Purchasing Power Parity) per QALY. According to our results, the dominant cost-effective strategy for hearing impairment screening was OAE plus AABR.

Methods: This population-based cross-sectional study utilizes data from the Child Mortality Surveillance System (CMSS) spanning from 2013 to 2022. The study population comprised all neonates (< 28 days old) with permanent residency in any of the 17 cities within the West Azerbaijan province who died within the stated period. Mortality rates, both all-cause and cause-specific, were determined per 1 000 live births for the years 2013, 2016, and 2022. Results: The investigation covered 3 689 reports of neonatal deaths (< 28 days old) from 2013 to 2022. Of these, 53% were males, with an average gestational age of 31.85 ± 5.56 weeks. Over 72% of the deaths occurred in preterm infants, and 69% were linked to cesarean section deliveries. Perinatal prematurity was the leading cause of death during the periods examined, with rates of 32.3%, 35.2%, and 36.8% in 2013, 2016, and 2022, respectively. The distribution of neonatal mortality across the province was uneven, with Poldasht city experiencing the highest mortality rates and Shot city the lowest (9.13 and 2.89 per 1 000 live births, respectively).

Severe HAdV infection leads to one of the most serious types of infantile RI, with rapidly progressive illness and a poor prognosis. Objectives: This study investigated the relationship between aspartate aminotransferase (AST) levels and the severity of HAdV RI in children. Methods: We collected clinical data from 665 cases of HAdV RI in children hospitalized at the pediatric ward of Changde First People's Hospital between January and December 2019. We analyzed the relationship between AST levels and disease severity. Results: Of the 665 HAdV-positive cases, 89.8% were < 6 years of age.

The 665 patients in the cohort were divided into a mild group (n = 477 cases, 71.73%) and a severe group (n = 188 cases, 28.27%). Univariate analysis showed that children with severe HAdV RI had a lower age of onset and lower hemoglobin and serum albumin levels while having higher platelet counts, lactic acid dehydrogenase, creatine kinase, creatine kinase isoenzyme, alanine aminotransferase, and AST levels compared to those with mild infections (P < 0.05). Multivariate analysis revealed that these factors were related to disease severity (P < 0.05). The ROC curve analysis indicated that the area under the AST curve was 0.782.

CD negatively affects oral and dental health. Objectives: This research explored the DMFT index and enamel defects (ED), as well as their association with oral health-related quality of life in children with CD. Methods: In this descriptive-analytical cross-sectional study, 50 children with CD (case group) and 50 healthy children (control group) were examined. The World Health Organization criteria were used to determine the DMFT index. Aine's classification was employed to diagnose ED, and the standard CHILD-Oral Impacts on Daily Performances scale was used to assess child oral health-related quality of life (COHRQoL). The Chi-Square test and Mann-Whitney test were utilized for data comparison. P-values < 0.05 were considered statistically significant. Results: The average DMFT was 2.58 ± 2.39 in the case group and 2.08 ± 1.61 in the control group. According to the Mann-Whitney U test, this difference was not statistically significant (P = .223). The frequency of ED in the case group was significantly higher at 52%, compared to 16% in the control group (P < .001). Additionally, there was a significant difference in the frequency of ED between boys and girls in the two groups (P < .001). The COHRQoL score in the case group, with an average of 24.44 ± 19.91, was significantly higher than that in the control group, which had an average of 13.35 ± 13.65 (P = .002).
